  Hereinafter, the structure of the wiring retractor 1 will be described with reference to the state where the wiring retractor 1 is installed on the roof. In the following explanation, regardless of the position of the eaves and ridges on the actual roof, the direction of the roof inclination is called the eaves direction, and the diagonally upper side along the eaves direction is along the ridge side, along the eaves direction. The diagonally lower side is called the eave side.

[First embodiment]
The wiring retractor 1 includes a main body member 2, a lower member 3, and a windproof member 65. The main body member 2 includes a base body 4, a cover body 5 that covers the base body 4, and a pressing member 47. 1 and 2 show the wiring retractor 1 installed on the roof, FIG. 3 shows the base body 4, FIGS. 4 and 5 show the cover body 5, FIG. 6 shows the pressing member 47, and FIG. FIG. 9 shows the member 3 and FIG.

  The base body 4 is formed from an appropriate material such as a resin material. The base body 4 is formed in a flat plate shape and a rectangular shape in plan view. The base body 4 is formed with a lead-out hole 21 penetrating vertically. A frame portion 45 protruding upward is formed on the upper surface of the base body 4 so as to surround the outlet hole 21. However, there is a portion where the outer frame portion 45 is not formed at a position on the eaves side with respect to the lead-out hole 21. This part is referred to as a notch 43. Furthermore, the base body 4 is formed with a plurality of fixing holes 44 penetrating vertically.

  A rib (outer rib 415) protruding upward is formed at the opening edge of the outlet hole 21, and the outer hole 415 surrounds the outlet hole 21 over the entire circumference. In a portion (referred to as an eaves side portion 416) located on the ridge side of the outer rib 415 from the lead-out hole 21, the upward projecting height is lower than the other portions. The upper surface of the eaves side portion 416 is a curved surface that curves downwardly from the ridge side toward the eave side. The curved surface of the eaves side portion 416 is formed so that the wiring 8 is not damaged by the eaves side portion 416 when the wiring 8 is disposed on the eaves side portion 416.

  Further, the base body 4 is formed with a plurality of guide ribs 22 protruding upward from the upper surface thereof. The plurality of guide ribs 22 are formed so as to extend linearly from the eaves side position of the outlet hole 21 to the vicinity of the notch 43 in the eaves ridge direction. The interval between the adjacent guide ribs 22 has an appropriate width such that the wiring 8 can be disposed between the guide ribs 22.

  Of the plurality of guide ribs 22, two outermost guide ribs 22 on both sides and a guide rib 22 located in the center are formed with fixing holes 46 for fixing the pressing member 47.

  The cover body 5 is formed from an appropriate material such as a metal plate material. The cover body 5 includes a top plate 51, a ridge piece 52, an eave piece 53, side pieces 54 and 54, lower pieces 55 and 55, and a draining piece 57. The top plate 51 is flat and has a rectangular shape in plan view, and the shape thereof matches the shape of the base body 4 in plan view. The ridge piece 52 is from the ridge side of the top plate 51, the eave piece 53 is from the ridge side of the top plate 51, and the side pieces 54 and 54 are sides on both sides in the direction orthogonal to the eave ridge direction of the top plate 51.

The draining piece 57 protrudes from the lower end of the ridge piece 52 and the ridge side end portions of the side pieces 54 and 54 toward the ridge side. The eaves piece 53 is formed with a notch 56 that communicates the inside and outside of the cover body 5 in the eaves-ridge direction.

  In addition, the ridge piece 52 may protrude so as to incline toward the ridge side obliquely downward from the ridge side of the top plate 51. In this case, even if water such as rainwater flowing on the roof reaches the wiring retractor 1, the water easily gets over the wiring retractor 1 along the inclination of the ridge piece 52, and the eaves are more than the wiring retractor 1. Flows to the side. For this reason, it becomes difficult for water to collect around the wiring retractor 1, and entry of water from the installation position of the wiring retractor 1 into the room is suppressed.

  The main body member 2 is configured by covering the base body 4 with the cover body 5 from above. The base body 4 is disposed inside the cover body 5 surrounded by the top plate 51, the ridge piece 52, the eave piece 53, and the side pieces 54 and 54. Inside the main body member 2, a hollow portion 23 is formed between the base body 4 and the cover body 5. The hollow portion 23 is a space surrounded by the base body 4, the top plate 51, the ridge piece 52, the eaves piece 53, and the side pieces 54 and 54 of the cover body 5. The lead-out hole 21 of the base body 4 communicates the hollow part 23 and the outer side below it in the vertical direction.

  The pressing member 47 is formed in a flat plate shape that is long in a direction orthogonal to the eaves ridge direction, and leg portions 48 that protrude downward are formed at both ends of the pressing member 47.

  In the main body member 2 configured as described above, a notch portion 56 formed in the eave piece 53 of the cover body 5 is overlapped on the outside of the notch portion 43 formed in the base body 4. Thereby, the introduction hole 24 which connects the hollow part 23 and the exterior is formed. The introduction hole 24 is formed at the eaves side end portion of the main body member 2 and communicates the hollow portion 23 and the outside thereof in the eaves ridge direction.

  Further, in the hollow portion 23, the plurality of guide ribs 22 of the base body 4 are formed so as to extend linearly in the eaves ridge direction from the eaves side position of the lead-out hole 21 to a position near the introduction hole 24.

  The lower member 3 includes a flat plate portion 31 and a cylindrical rib 32. The flat plate portion 31 is formed in a flat plate shape and a rectangular shape in plan view. A communication hole 33 penetrating vertically is formed in the flat plate portion 31. The communication hole 33 is formed in a shape that matches the outlet hole 21. The cylindrical rib 32 is formed so as to protrude upward from the peripheral edge of the communication hole 33 of the flat plate portion 31. The rib 32 is formed in a shape that can be inserted into the outlet hole 21. The flat plate portion 31 is formed with a plurality of fixing holes 36 through which fixing tools such as screws and nails are inserted.

  The windproof member 65 includes a fixing portion 66 and a windproof piece 69. The fixing portion 66 is fixed to the eaves side end portion of the roofing material. The windproof piece 69 protrudes upward from the eaves side end portion of the fixed portion 66. The windproof member 65 is formed, for example, by bending a metal plate. The fixing portion 66 of the wind-proof member 65 is arranged in a state of being fixed to the eaves side end portion of the roof material, and is arranged so as to be superimposed on the upper surface of the roof material, and is superimposed on the lower surface of the roof material. It consists of a lower piece 68. The windproof piece 69 is formed from the eaves side end of the upper piece 67 to the eaves side end of the lower piece 68, and is formed to protrude upward from the upper piece 67.

  A roof structure provided with the wiring retractor 1 will be described.

  The roof base 6 is composed of a field board or the like. A waterproof sheet such as asphalt roofing may be further provided on the base plate. A through hole 61 having a shape that matches the outlet hole 21 and the communication hole 33 is formed in the roof base 6.

  A lower member 3 and a plurality of roof materials 7 are installed on the roof base 6. The roof material 7 has a flat plate shape, and is formed of, for example, a slate material.

  A plurality of roofing materials 7 (referred to as a first-line roofing material 71 for convenience) are installed side by side in the direction orthogonal to the eaves building direction on the roof base 6 and on the eaves side of the through hole 61. The lower member 3 is installed at a position on the base plate where the through hole 61 is formed. The lower member 3 is installed by fixing the flat plate portion 31 to the roof base 6 with a fixing tool such as a screw or a nail. The lower member 3 is installed at a position where the communication hole 33 and the through hole 61 of the roof base 6 overlap each other.

  On the roof base 6, a plurality of roof materials 7 (referred to as a second row roof material 72 for convenience) are further installed on the ridge side portion of the installed first row roof material 71. The roof material 72 in the second row is also installed side by side in a direction orthogonal to the eaves direction. Of the roof material 72 in the second row, the roof material 72 that overlaps the lower member 3 is formed with a notch or an opening (not shown) at a position that overlaps the cylindrical rib 32. Through this cutout or opening, the cylindrical rib 32 protrudes above the roof material 72 in the second row.

  On the roof base 6, a plurality of roof materials 7 (referred to as a third row roof material 73 for convenience) are further placed on the ridge side portion of the second row roof material 72. The roof material 73 in the third row is also installed side by side in a direction orthogonal to the eaves direction. Of the roof material 73 in the third row, the roof material 73 that overlaps the lower member 3 is formed with a notch or an opening (not shown) at a position that overlaps the cylindrical rib 32. Through this cutout or opening, the cylindrical rib 32 protrudes above the roof material 73 in the third row.

  The base body 4 is installed on the roof material 73 in the third row. The base body 4 is installed by, for example, driving a fixing tool such as a screw or a nail into the third row of roofing material 73 through the fixing hole 44. The base body 4 is installed at a position where the lead-out hole 21 and the communication hole 33 of the lower member 3 overlap each other, and the cylindrical rib 32 is inserted into the lead-out hole 21.

  The cover body 5 is installed so as to cover the base body 4. Thereby, the main body member 2 is comprised by the cover body 5 and the base body 4 as above-mentioned. The cylindrical rib 32 of the lower member 3 is inserted into the outlet hole 21 and protrudes into the hollow portion 23. The cover body 5 is fixed to the base body 4 by a fixture 9 such as a screw or a nail. The fixing tool 9 is driven so as to pass through a position where the ridge piece 52, the eaves piece 53, the side pieces 54 and 54 of the cover body 5 and the outer frame portion 45 of the base body 4 overlap.

  In particular, as shown in FIG. 1, the fixture 9 preferably penetrates the base body 4 and the cover body 5 along the surface of the roof base 6 in a direction orthogonal to the eaves-ridge direction. That is, the fixture 9 is configured such that the side pieces 54 and 54 and the outer frame portion 45 are orthogonal to the eaves-ridge direction at a position where the side pieces 54 and 54 of the cover body 5 and the outer frame portion 45 of the base body 4 overlap. It is preferably driven so as to penetrate in the direction.

  On the roof base 6, a plurality of roof materials 7 (referred to as a fourth row roof material 74 for convenience) are further placed on the ridge side portion of the third row roof material 73. The roof material 74 in the fourth row is also installed side by side in a direction orthogonal to the eaves-ridge direction. Among these fourth row roof materials 74, the roof material 74 installed on the ridge side of the main body member 2 is installed so as to overlap the drain piece 57 of the cover body 5. The cover body 5 may be installed before the fourth row of roofing materials 74 is installed, but may be installed after the fourth row of roofing materials 74 is installed. When the cover body 5 is installed after the fourth row roof material 74 is installed, the draining piece 57 of the cover body 5 is located between the third row roof material 73 and the fourth row roof material 74. It is inserted.

  The windproof member 65 is installed at the eaves side end of the third row roofing material 73 on which the main body member 2 is installed. The windproof member 65 is installed by sandwiching the eaves side end portion of the roofing material 73 between the upper piece 67 and the lower piece 68 of the fixing portion 66. The windproof member 65 is disposed at a position closer to the eaves than the main body member 2, and the windproof piece 69 of the windproof member 65 projects upward from the upper surface of the roof material 73. The windbreak piece 69 is disposed at a position facing the main body member 2 and the introduction port 4 of the main body member 2 with an interval in the eaves-ridge direction.

  Thus, in the state where the wiring retractor 1 is installed on the roof, the introduction hole 24 communicates the hollow portion 23 and the outdoors, and the lead-out hole 21 passes through the communication hole 33 and the through hole 61 of the roof base 6. The hollow portion 23 communicates with the indoor.

  The plurality of wirings 8 sequentially pass through the introduction hole 24, the hollow portion 23, the lead-out hole 21, and the communication hole 33 of the wiring lead-in tool 1 from the outside, and further pass through the through-hole 61 of the roof base 6 and be drawn indoors. It is. The plurality of wirings 8 are introduced into the hollow portion 23 from the introduction hole 24 and are arranged one by one between the guide ribs 22, thereby being positioned and fixed in the hollow portion 23.

  The plurality of wirings 8 introduced into the hollow portion 23 are further led indoors from the hollow portion 23 through the lead-out hole 21, the communication hole 33, and the through-hole 61 of the roof base 6.

  The wiring 8 is pulled in, for example, in a state where the base body 4 is installed on the roofing material 7 and the base body 4 is not covered with the cover body 5. In this case, since the wiring 8 is pulled in with the lead-out hole 21 and the guide rib 22 exposed to the outdoors, the workability is improved.

  In a state where the wiring 8 is sandwiched and fixed between the guide ribs 22 and the wiring 8 is further pressed between the guide ribs 22 by the pressing member 47 as shown in FIG. Furthermore, it becomes difficult to drop off. The holding member 47 is disposed above the guide rib 22 so as to close the gap between the guide ribs 22, and each leg portion 47 of the holding member 47 is further outside the two guide ribs 22 located on the outermost sides on both sides. Each is arranged. A fixing tool such as a nail or a screw is driven into the pressing member 47, and the fixing member 47 is fixed by driving the fixing tool into the fixing hole 46 of the guide rib 22.

  Such a roof structure is provided when the rooftop equipment 10 such as the solar cell module 101 is installed on the roof and the wiring 8 connected to the rooftop equipment 10 is drawn indoors.

  FIG. 10 shows a state in which the solar cell module 101 is installed on the roof. On the roof material 7, a plurality of frame members 102 that are long in the eave building direction are installed side by side in a direction orthogonal to the eave building direction. A plurality of solar cell modules 101 are installed on the frame member 102 in a matrix shape in the eave building direction and in a direction orthogonal to the eave building direction. Thereby, the solar cell module 101 is installed above the roof material 7 so that there is a gap between the solar cell module 101 and the roof material 7. The wiring 8 connected to the solar cell module 101 is routed between the solar cell module 101 and the roof material 7 and is drawn indoors from the wiring retractor 1.

  When the solar cell modules 101 are installed in this way, one wiring lead-in tool 1 is provided for each of the fixed number of solar cell modules 101, and the wiring connected to the fixed number of solar cell modules 101 is provided. 8 may be drawn indoors from one wiring drawing tool 1. In this embodiment, even when a plurality of wires 8 routed from different positions are drawn indoors from one wire drawing tool 1, the wires 8 are positioned by the guide ribs 22 in the hollow portion 23 in this embodiment. Therefore, the plurality of wirings 8 can be easily accommodated in the hollow portion 23.

  Further, since the plurality of wirings 8 are arranged and arranged in the hollow portion 23, stress from the plurality of wirings 8 to the wiring retractor 1 is difficult to concentrate, and thus the wiring 8 and the wiring retractor 1 are not easily damaged. Become. Furthermore, at the time of maintenance after the solar cell module 101 is installed, the correspondence relationship between the wiring 8 and the solar cell module 101 to which the wiring 8 is connected can be easily recognized. It becomes easy.

  Often, a plurality of indoor equipment devices 10 are installed on the roof. In such a case, a plurality of wires 8 are simultaneously drawn indoors from the wire retractor 1. For this reason, the operation of pulling in the wiring 8 at the time of construction becomes complicated, and it becomes difficult to distinguish between the plurality of wirings 8 at the time of maintenance after the construction. Further, the stress applied to the wiring retractor 1 from the plurality of wirings 8 is concentrated at one point, and there is a possibility that the wiring retractor 1 is damaged. However, in the present embodiment, since the guide ribs 22 for guiding the plurality of wires 8 one by one from the introduction hole 24 to the lead-out hole 21 are formed in the hollow portion 23, the wire drawing tool 1 is used. Then, when the work for drawing a plurality of wires 8 from the outdoor to the indoor is performed on the roof, the work for drawing the wires 8 is facilitated and the maintenance after the work is facilitated, and the wire drawing tool 1 from the plurality of wires 8 is provided. It becomes difficult for stress to concentrate.

  Moreover, in this embodiment, in order for water, such as rain water, to infiltrate indoors from the ridge side of the wiring retractor 1 through the through-hole 61 of the roof base 6, the water is first drained 57 and the fourth row roofing material. It is necessary to enter the inside of the wiring retractor 1 by moving toward the eave side between the draining piece 57 and the roof material 73 of the third row. For this reason, the movement of water to the through hole 61 of the roof base 6 is inhibited by the draining piece 57, and the intrusion of water into the room is suppressed.

  Further, since the lower member 3 is installed on the roof base 6, movement of the water on the roof base 6 to the through hole 61 is blocked by the lower member 3. Even if water moves toward the through hole 61 on the lower member 3, the movement of this water is blocked by the cylindrical rib 32. Even when water enters the hollow portion 23, the movement of the water to the through hole 61 is blocked by the cylindrical rib 32. Thereby, the penetration | invasion of the water to an indoor is further suppressed.

  As shown in FIG. 8A, a sealing material 34 may be provided on the lower surface of the flat plate portion 31 of the lower member 3. The sealing material 34 is formed so as to surround the entire periphery of the communication hole 33. In this case, the flow of water that passes between the lower member 3 and the roof base 6 and reaches the through hole 61 is hindered by the sealing material 34, and water intrusion into the room is further suppressed. Further, the sealing material 35 may be provided so as to overlap the upper surface of the lower member 3. This sealing material 35 is formed so as to surround the entire circumference of the cylindrical rib 32. In this case, the water flowing on the lower member 3 gets over the cylindrical rib 32 and enters the through hole 61 by the sealing material 35, and the intrusion of water into the room is further suppressed.

  Further, as shown in FIG. 8B, the sealing material 34 may be overlapped on the entire lower surface of the flat plate portion 31. In this case, when the lower member 3 is fixed to the roof base 6 by the fixing tool, the sealing material 34 is provided at a position where the fixing tool is driven, so that water enters the indoor from the position where the fixing tool is driven. This is further suppressed. In addition, if the sealing material 34 is overlapped on the lower surface of the flat plate portion 31 at a position surrounding at least the entire periphery of the communication hole 33 and a position where the fixing tool is driven, the sealing material 34 is overlapped on the entire lower surface of the flat plate portion 31. It does not have to be.

  Moreover, when the fixing tool 9 in the main body member 2 penetrates the base body 4 and the cover body 5 along the surface of the roof base 6 in the direction orthogonal to the eaves ridge direction, the wiring retractor 1 is installed. Water flows on the third roofing material 7 along the roof slope toward the eaves, or water is blown up on the third roofing material 7 by wind or the like, and flows along the roof slope toward the ridge side. Even so, it becomes difficult for this water to enter the hollow portion 23 through the position where the fixture 9 in the base body 4 and the cover body 5 penetrates. This further suppresses the intrusion of water indoors.

  In addition, the hollow portion 23 of the wiring retractor 1 is opened to the outside through the introduction hole 24, and the introduction hole 24 opens at the end face on the eaves side of the wiring retractor 1. For this reason, even if water flows on the roof material 7 along the inclination of the roof to the eaves side, this water is less likely to enter the hollow portion 23 through the introduction hole 24. Further, even when water is blown up by wind or the like on the roofing material 7 and flows toward the ridge along the slope of the roof, the wind and rain is hindered by the windbreaking piece 69 of the windbreaking member 65, so that water is applied to the main body member 2. It becomes difficult to be sprayed. Further, since the windbreak piece 69 faces the introduction port 24 in the eaves ridge direction, blowing of wind and rain into the introduction port 24 is hindered by the windbreak piece. This further suppresses the intrusion of water indoors.

  Even if water enters the vicinity of the lead-out hole 21 on the base body 4, the lead-out hole 21 is surrounded by the surrounding ribs 415. Intrusion into the is suppressed.

  The wiring retractor 1 may be provided with a sealing material 90 (91, 92) made of a foam material or the like in the vicinity of the introduction hole 24 in the hollow portion 23 (see the second embodiment, FIGS. 17 and 18). ). For example, sealing materials 91 and 92 are provided on the cover body 5 and the base body 4, respectively, the two sealing materials 91 and 92 face each other inside the introduction hole 24, and the wiring 8 is provided between the sealing materials 91 and 92. Sandwiched. In this case, entry of water into the hollow portion 23 through the introduction hole 24 is further suppressed. The sealing material 90 only needs to close the introduction hole 21 in a state where at least the wiring 8 is disposed so as to pass through the introduction hole 24. This effectively suppresses water from entering the hollow portion 23 along the wiring 8. For example, when the wiring 8 is not arranged, a gap is formed between the two sealing materials 91 and 92. When the wiring 8 is arranged, the gap may be closed by the wiring 8, but preferably In addition, it is desirable that the gap is not generated between the two sealing materials 91 and 92 even when the wiring 8 is not disposed.

[Second Embodiment]
The wiring retractor 1 includes a main body member 2 and a lower member 3. The main body member 2 includes a base body 4, a cover body 5 that covers the base body 4, a pressing member 47, and a sealing material 90. 11 shows the wiring retractor 1 installed on the roof, FIGS. 12 and 13 show the base body 4, FIG. 14 shows the cover body 5, FIG. 15 shows the pressing member 47, and FIG. 16 shows the lower member 3. FIG. 17 shows the sealing material 90, respectively.

  The base body 4 shown in FIGS. 12 and 13 is formed from an appropriate material such as a resin material. The base body 4 is formed in a flat plate shape and a rectangular shape in plan view.

  The base body 4 is formed with a lead-out hole 21 penetrating vertically. A rib (outer rib 415) that protrudes upward is formed at the opening edge of the lead-out hole 21, and the lead-out hole 21 is surrounded over the entire circumference by the outer rib 415. In a part (referred to as an eaves side part 416) located on the eaves side with respect to the lead-out hole 21 in the outer rib 415, the upward protruding height is lower than the other parts. The upper surface of the eaves side portion 416 is a curved surface that curves downwardly from the ridge side toward the eave side. The curved surface of the eaves side portion 416 is formed so that the wiring 8 is not damaged by the eaves side portion 416 when the wiring 8 is disposed on the eaves side portion 416. Further, an elastic member 95 (see FIG. 12A) is attached on the upper surface of the eaves side portion 416 by bonding. The elastic member 95 has a flat plate shape and is attached so as to be curved along the curved surface of the eaves side portion 416. This elastic member 95 has elasticity. The elastic member 95 is preferably formed of an appropriate rubber such as EPDM rubber or an elastomer, or is preferably a porous member having closed cells or semi-closed cells. However, the material of the elastic member 95 is not limited to this.

  An outer frame portion 45 protruding upward is formed on the upper surface of the base body 4 so as to surround the outlet hole 21. However, there is a portion where the outer frame portion 45 is not formed at a position on the eaves side with respect to the lead-out hole 21. This part is referred to as a notch 43. A part of the outer frame part 45 constitutes a water flow control part 412. This water flow control unit 412 is on the ridge side with respect to the outlet hole 21, and includes two ribs 410 and 411 that are long in the direction intersecting the eaves ridge direction. These two ribs 410 and 411 are arranged at intervals in the eaves-ridge direction. The two ribs 410 and 411 are formed with a plurality of drainage inlet holes 413 penetrating in the direction of the eaves and open upward. The drain holes 413 formed in the ribs 410 and 411 are arranged so as to be shifted from each other so as not to line up in the eaves-ridge direction. Although the position of the drainage inlet hole 413 is set as appropriate, in this embodiment, the drainage inlet hole 413 is formed at the center of the rib 410 on the ridge side. Further, the ridge-side rib 410 and the eaves-side rib 411 are formed with drainage inlet holes 413 at both ends on the outer side of the outlet hole 21, and the ridge-side rib 410 has a drainage inlet. The hole 413 is formed at a position shifted outward from the drain hole 413 in the eave-side rib 411. Note that the number of ribs constituting the water flow control unit 412 is not limited to two, and the water flow control unit 412 may be formed of a plurality of three or more ribs arranged in the eaves-ridge direction. Further, the outer frame portion 45 has a drain outlet hole 414 that penetrates in the direction intersecting the eave building direction and opens upward at the eave side end portions on both sides in the direction orthogonal to the eave building direction. Is formed. Furthermore, the base body 4 is formed with a plurality of fixing holes 44 penetrating vertically. The fixing hole 44 is opened by a convex part 417 formed on the upper surface of the base body 4 and projecting upward (see FIG. 12F).

  Further, the base body 4 is formed with a plurality of guide ribs 22 protruding upward from the upper surface thereof. The plurality of guide ribs 22 are formed so as to extend linearly in the direction of the eaves ridge from the position on the eave side with respect to the outlet hole 21 toward the notch 43. The interval between the adjacent guide ribs 22 has an appropriate width such that the wiring 8 can be disposed between the guide ribs 22.

  Of the plurality of guide ribs 22, fixing holes 46 for fixing the pressing member 47 are respectively formed in the two guide ribs 22 positioned on the outermost sides on both sides.

  As shown in FIG. 13, the guide rib 22 may have a convex portion 25 for fixing the wiring 8. The convex portion 25 is formed on the opposing surfaces of the adjacent guide ribs 22. In the example shown in FIG. 13, the convex portion 25 is one convex line extending in the vertical direction, but the shape of the convex portion 25 is not particularly limited. When such a convex part 25 is formed, when the wiring 8 is arranged one by one between the adjacent guide ribs 22, the convex part 25 presses the wiring 8 so that the wiring 8 is firmly positioned. It is made.

  Even if the base body 4 has markings 418, 419, and 420 serving as an index of the wiring 8 disposed between the guide ribs 22 at an appropriate position such as a gap between the adjacent guide ribs 22 or on the guide rib 22. Good. In this case, it becomes easy to arrange a plurality of types of wirings 8 in the gaps between the predetermined guide ribs 22. The markings 418, 419, and 420 are formed by printing, for example, or formed by uneven processing on the surface of the base body 22. In the example shown in FIG. 13, markings 418 representing numbers serving as indices of the wiring 8 are formed in the gaps between the adjacent guide ribs 22. A marking 419 representing a ground symbol and a marking 420 representing a ground character are respectively formed on the guide ribs 22 on both sides of the gap where the ground wire is disposed. Of course, the formation positions and shapes of the markings 418, 419, and 420 may be other than those shown in FIG.

  The cover body 5 shown in FIG. 14 is formed from an appropriate material such as a metal plate material. The cover body 5 includes a top plate 51, a ridge piece 52, an eave piece 53, side pieces 54 and 54, lower pieces 55 and 55, an upper piece 58 and a draining piece 57. The top plate 51 is flat and rectangular in plan view. The ridge piece 52 protrudes obliquely downward from the ridge side of the top plate 51 toward the ridge side. Thus, if the ridge piece 52 protrudes diagonally downward, even if water such as rain water flowing on the roof reaches the wiring retractor 1, the water pulls the wiring retractor 1 along the inclination of the ridge piece 52. It gets over easily and flows to the eaves side rather than the wiring retractor 1. For this reason, it becomes difficult for water to collect around the wiring retractor 1, and entry of water from the installation position of the wiring retractor 1 into the room is suppressed. Note that the ridge piece 52 may protrude downward from the ridge side of the top plate 51. The eaves piece 53 protrudes downward from the ridge side of the top plate 51, and the side pieces 54, 54 protrude downward from the respective sides of the top plate 51 and the ridge piece 52 in the direction orthogonal to the eave ridge direction. The upper piece 58 protrudes from each side on both sides of the top board 51 in the direction orthogonal to the eaves-ridge direction to the outside direction orthogonal to the eaves-ridge direction. The upper piece 58 is formed so that the water flowing on the upper surface of the cover body 5 does not easily enter the side portion of the cover body 5. When such water wraparound is suppressed, the intrusion of water from the side of the cover body 5 into the cover body 5 is suppressed. Further, for example, when the cover body 5 is manufactured by bending a metal plate, a pinhole-like hole is formed near the ridge side end of the side piece 54 or the boundary between the top plate 51 and the ridge piece 52 in the side piece 54. However, even if there is such a hole, it is possible to prevent water from entering the cover body 5 from this hole. The lower pieces 55, 55 protrude from the lower ends of the side pieces 54, 54 in the outer direction perpendicular to the eaves ridge direction. The draining piece 57 protrudes from the lower end of the ridge piece 52 and the ridge side end portions of the side pieces 54 and 54 toward the ridge side. The eaves piece 53 is formed with a notch 56 that communicates the inside and outside of the cover body 5 in the eaves-ridge direction.

  Furthermore, the wiring retractor 1 is provided with a sealing material 90 (91, 92) (see FIGS. 17 and 18) made of a foam material or the like in the vicinity of the introduction hole 24 in the hollow portion 23. Sealing materials 90 (91, 92) are provided on the cover body 5 and the base body 4, respectively. Two sealing materials 91, 92 are vertically opposed inside the introduction hole 24, and a wiring is provided between the sealing materials 91, 92. 8 is sandwiched. In this case, entry of water into the hollow portion 23 through the introduction hole 24 is further suppressed. The sealing material 90 only needs to close the introduction hole 21 in a state where at least the wiring 8 is disposed so as to pass through the introduction hole 24. This effectively suppresses water from entering the hollow portion 23 along the wiring 8. For example, when the wiring 8 is not arranged, a gap is formed between the two sealing materials 91 and 92. When the wiring 8 is arranged, the gap may be closed by the wiring 8, but preferably In addition, it is desirable that the gap is not generated between the two sealing materials 91 and 92 even when the wiring 8 is not disposed. The sealing material 90 (91, 92) has elasticity. Furthermore, it is preferable that the sealing material 90 (91, 92) is difficult to transmit water. Therefore, the sealing material 90 (91, 92) is preferably formed from an appropriate rubber such as EPDM rubber or an elastomer, or is preferably a porous member having closed cells or semi-closed cells. However, the material of the sealing material 90 (91, 92) is not limited to this.

  The sealing material 91 provided on the base body 4 is attached between the guide rib 22 and the notch 43 on the base body 4 by being bonded to a position facing the notch 43 (FIG. 12A). )reference). On the upper surface of the sealing material 91, a concave stripe 93 is formed so as to extend in the eaves-ridge direction. A plurality of recesses 93 are formed, and the plurality of recesses 93 are arranged in a direction orthogonal to the eaves-ridge direction. The plurality of concave stripes 93 are formed at positions that coincide with the gaps between the adjacent guide ribs 22. The cross-sectional shape of the concave stripe 93 may be a semicircular shape as shown in FIG. 17, a semi-elliptical shape long in the eaves direction as shown in FIG. 18, or any other appropriate shape. May be. The sealing material 92 provided on the cover body 5 is attached to the lower surface of the ceiling plate 51 of the cover body 5 by being adhered to a position matching the sealing material provided on the base body 4 (FIG. 14A). reference). A recess 94 is formed on the lower surface of the sealing material 92 so as to extend in the eaves-ridge direction. A plurality of recesses 94 are formed, and the plurality of recesses 94 are arranged in a direction orthogonal to the eaves-ridge direction. The groove 94 of the sealing material 92 provided on the cover body 5 is formed at a position that matches the groove 93 of the sealing material 91 provided on the base body 4. The cross-sectional shape of the recess 94 of the sealing material 92 provided on the cover body 5 is also a semi-elliptical shape that is long in the eaves-ridge direction as shown in FIG. 18, even if it is a semi-circular shape as shown in FIG. Or any other suitable shape.

  The pressing member 47 shown in FIG. 15 is formed in a flat plate shape, and leg portions 48 projecting downward are formed at both end portions and a ridge side end portion. As will be described later, the leg portion 48 is outside the outer ribs 415 (excluding the eaves side portion 416) of the base body 4 and further outside the two guide ribs 22 positioned at the outermost sides on both sides of the plurality of guide ribs 22. Placed in. Further, an elastic member 96 is attached to the lower surface of the pressing member 47 (see FIG. 15A). The elastic member has elasticity, and is formed of, for example, the same material as the elastic member attached to the eaves side portion 416 in the surrounding rib 415 of the base body 4. The elastic member in the pressing member 47 is attached at a position that matches the elastic member attached to the eaves side portion 416 of the base body 4. Further, a fixing hole 49 is formed in the pressing member 47 at a position that matches the fixing hole 46 in the base body 4.

  The seal member 91 is attached to the base body 4, the seal member 92 is attached to the cover body 5, the pressing member 47 is attached to the base body 4, and the base body 4 is covered with the cover body 5 from above, so that the main body member 2 is configured.

  When the pressing member 47 is attached to the base body 4, the leg portions 48 of the pressing member 47 are outside the outer ribs 415 (excluding the eaves side portion 416) of the base body 4 and the outermost sides on both sides of the plurality of guide ribs 22. The fixing hole 49 of the pressing member 47 is arranged at a position that coincides with the fixing hole 46 in the base body 4. In this state, the pressing member 47 is fixed to the base body 4 by driving a fixing tool such as a nail or a screw into the fixing hole 49 and the fixing hole 46. As a result, the pressing member 47 is disposed above the outer rib 415, and the pressing member 47 is in contact with the upper end of the outer rib 415 except for the eaves side portion 416, and is generated between the pressing member 47 and the eaves side portion 416. The gap communicates with the outlet hole 21. Further, the pressing member 47 is disposed above the guide rib 22 so as to close the gap between the guide ribs 22.

  When the base body 4 is covered with the cover body 5 from above, the base body 4 is disposed inside the cover body 5 surrounded by the top plate 51, the ridge piece 52, the eave piece 53, and the side pieces 54 and 54. Inside the main body member 2, a hollow portion 23 is formed between the base body 4 and the cover body 5. The hollow portion 23 is a space surrounded by the base body 4, the top plate 51, the ridge piece 52, the eaves piece 53, and the side pieces 54 and 54 of the cover body 5. In this state, the lead-out hole 21 of the base body 4 communicates the hollow portion 23 with the outer side below the inner side of the surrounding rib 415 and the gap between the pressing member 47 and the eaves side portion 416.

  In the main body member 2 configured as described above, a notch portion 56 formed in the eave piece 53 of the cover body 5 is overlapped on the outside of the notch portion 43 formed in the base body 4. Thereby, the introduction hole 24 which connects the hollow part 23 and the exterior is formed. The introduction hole 24 is formed at the eaves side end portion of the main body member 2 and communicates the hollow portion 23 and the outside thereof in the eaves ridge direction.

  Further, in the hollow portion 23, the plurality of guide ribs 22 of the base body 4 are formed so as to extend linearly in the eave ridge direction from the eaves side position of the lead-out hole 21 to a position near the introduction hole 24.

  Further, in the hollow portion 23, a sealing material 90 (91, 92) is disposed between the guide rib 22 and the introduction hole 24. The two sealing materials 91, 92 overlap each other in an elastic manner, and are in elastic contact with each other. The concave strip 94 of the sealing material 92 provided on the cover body 5 and the concave strip of the sealing material 91 provided on the base body 4. A plurality of holes for communicating the inside of the hollow portion 23 with the outside are formed by facing 93. Except for this hole, the introduction hole 24 is closed by the sealing material 90 (91, 92). More preferably, the two seal members 91, 92 are pressed against each other and elastically compressed, so that the recess 94 of the seal member 92 provided on the cover body 5 and the recess of the seal member 91 provided on the base body 4 are provided. The strips 93 are also in elastic contact with each other. In this case, the hole as described above is not formed between the two sealing materials 91 and 92, and the entire introduction hole 24 is closed only by the sealing material 90 (91, 92).

  The lower member 3 shown in FIG. 16 includes a flat plate portion 31 and a cylindrical rib 32. The flat plate portion 31 is formed in a flat plate shape and a rectangular shape in plan view. A communication hole 33 penetrating vertically is formed in the flat plate portion 31. The communication hole 33 is formed in a shape that matches the outlet hole 21. The cylindrical rib 32 is formed so as to protrude upward from the peripheral edge of the communication hole 33 of the flat plate portion 31. The rib 32 is formed in a shape that can be inserted into the outlet hole 21. The flat plate portion 31 is formed with a plurality of fixing holes 36 through which fixing tools such as screws and nails are inserted.

  The flat plate portion 31 of the lower member 3 is formed with notched indicators 37 at both edges in the eave building direction, and these two indicators 37 are arranged in the eave building direction. The flat plate portion 31 is formed with notched indicators 37 at both end edges in a direction orthogonal to the eaves-ridge direction, and these two indicators 37 are arranged in a direction orthogonal to the eaves-ridge direction. . Such an index 37 can be used for alignment of the lower member 3 when the lower member 3 is installed on the roof. For example, an operator who installs the lower member 3 on the roof base 6 easily positions the lower member 3 by aligning the index 37 with the abutting position of the roof material 7 or aligning the marking line drawn in advance. Can be combined. The shape and position of the indicator 37 are not limited to the form shown in FIG.

  A roof structure provided with the wiring retractor 1 will be described.

  The roof base 6 is composed of a field board or the like. A waterproof sheet such as asphalt roofing may be further provided on the base plate. A through hole 61 having a shape that matches the outlet hole 21 and the communication hole 33 is formed in the roof base 6.

  A lower member 3 and a plurality of roof materials 7 are installed on the roof base 6. The roof material 7 has a flat plate shape, and is formed of, for example, a slate material.

  A plurality of roofing materials 7 (referred to as a first-line roofing material 71 for convenience) are installed side by side in the direction orthogonal to the eaves building direction on the roof base 6 and on the eaves side of the through hole 61. The lower member 3 is installed at a position on the base plate where the through hole 61 is formed. The lower member 3 is installed by fixing the flat plate portion 31 to the roof base 6 with a fixing tool such as a screw or a nail. The lower member 3 is installed at a position where the communication hole 33 and the through hole 61 of the roof base 6 overlap each other.

  On the roof base 6, a plurality of roof materials 7 (referred to as a second row roof material 72 for convenience) are further installed on the ridge side portion of the installed first row roof material 71. The roof material 72 in the second row is also installed side by side in a direction orthogonal to the eaves direction. Of the roof material 72 in the second row, the roof material 72 that overlaps the lower member 3 is formed with a notch or an opening (not shown) at a position that overlaps the cylindrical rib 32. Through this cutout or opening, the cylindrical rib 32 protrudes above the roof material 72 in the second row.

  On the roof base 6, a plurality of roof materials 7 (referred to as a third row roof material 73 for convenience) are further placed on the ridge side portion of the second row roof material 72. The roof material 73 in the third row is also installed side by side in a direction orthogonal to the eaves direction. Of the roof material 73 in the third row, the roof material 73 that overlaps the lower member 3 is formed with a notch or an opening (not shown) at a position that overlaps the cylindrical rib 32. Through this cutout or opening, the cylindrical rib 32 protrudes above the roof material 73 in the third row.

  On the roof base 6, a plurality of roof materials 7 (referred to as a fourth row roof material 74 for convenience) are further placed on the ridge side portion of the third row roof material 73. The roof material 74 in the fourth row is also installed side by side in a direction orthogonal to the eaves-ridge direction.

  The base body 4 is installed on the roof material 73 in the third row. The base body 4 is installed by, for example, driving a fixing tool such as a screw or a nail into the third row of roofing material 73 through the fixing hole 44. The base body 4 is installed at a position where the lead-out hole 21 and the communication hole 33 of the lower member 3 overlap each other, and the cylindrical rib 32 is inserted into the lead-out hole 21.

  In this state, the plurality of wirings 8 are provided so as to sequentially pass through the lead-out hole 21 and the communication hole 33 from the outdoors, and further pass through the through-hole 61 of the roof base 6 and be drawn indoors. Further, the plurality of wires 8 are positioned and fixed by being arranged one by one between the guide ribs 22.

  Subsequently, the pressing member 47 is attached to the base body 4. As a result, the plurality of wires 8 are held by being sandwiched between the base body 4 and the pressing member 47, the movement of the arrangement position of the wires 8 is restricted, and the plurality of wires 8 are prevented from being twisted. At this time, it is preferable to sandwich the wiring 8 between the eaves side portion 416 of the surrounding rib 415 and the pressing member 47 so that the eaves side portion 416 and the pressing member 47 are in contact with the wiring 8. The movement of 8 is sufficiently restrained. At this time, if the elastic members 95 and 96 are attached to the eaves side portion 416 and the holding member 47, respectively, the eaves side portion 416 and the holding member 47 are not in direct contact with the wiring 8, and the elastic members 95 and 96 are attached. Will be elastically contacted with each other, thereby preventing the wiring 8 from being damaged. Furthermore, since the pressing member 47 is disposed above the guide rib 22 so as to close the gap between the guide ribs 22, the pressing member 47 presses the wiring 8 between the guide ribs 22, thereby It becomes more difficult for the wiring 8 to fall off from the gap. Moreover, since the pressing member 47 covers the upper part of the outlet hole 21, the intrusion of water from the outlet hole 21 into the room is suppressed.

  Subsequently, the cover body 5 is installed so as to cover the base body 4. At this time, the draining piece 57 of the cover body 5 is inserted between the roof material 73 in the third row and the roof material 74 in the fourth row. Thus, the main body member 2 is configured.

  The cover body 5 is fixed to the base body 4 by a fixture 9 such as a screw or a nail. The fixing tool 9 is driven so as to pass through a position where the ridge piece 52, the eaves piece 53, the side pieces 54 and 54 of the cover body 5 and the outer frame portion 45 of the base body 4 overlap. In particular, as shown in FIG. 11, the fixture 9 preferably penetrates the base body 4 and the cover body 5 along the surface of the roof base 6 in a direction orthogonal to the eaves-ridge direction. That is, the fixture 9 is configured such that the side pieces 54 and 54 and the outer frame portion 45 are orthogonal to the eaves-ridge direction at a position where the side pieces 54 and 54 of the cover body 5 and the outer frame portion 45 of the base body 4 overlap. It is preferably driven so as to penetrate in the direction.

  When the wiring 8 fixture is installed in this way, the plurality of wirings 8 are connected to the gap between the introduction hole 24, the hollow portion 23, the holding member 47, and the eaves side portion 416 of the wiring retractor 1 from the outside. The lead hole 21 and the communication hole 33 are sequentially passed through, and further passed through the through hole 61 of the roof base 6 so as to be drawn indoors.

  Further, the movement of the wiring 8 is also restricted by being sandwiched between the sealing materials 90 (91, 92). At this time, when a hole is formed between the concave stripe 94 of the sealing material 92 and the concave stripe 93 of the sealing material 91 provided in the base body 4, the wiring 8 is disposed in this hole. The two sealing materials 91 and 92 are elastically contacted with the wiring 8 by the concave stripes 93 and 94, so that the hole is filled with the wiring 8. For this reason, the whole introduction hole 24 is blocked by the sealing material 90 (91, 92) and the wiring 8, thereby suppressing the intrusion of water from the introduction hole 24 into the wiring retractor 1. In addition, when the groove 94 of the sealing material 92 provided on the cover body 5 and the groove 93 of the sealing material 91 provided on the base body 4 are in elastic contact with each other, the hole as described above is not formed. The wiring 8 is arranged so as to be in elastic contact with the sealing material 90 (91, 92) by being sandwiched between the two concave stripes 93, 94. In this case, it is assumed that the wiring 8 is positioned by the two concave stripes 93 and 94 and the position movement is effectively suppressed, and there is a portion where the wiring 8 is not disposed between the two concave stripes 93 and 94. In addition, the introduction hole 24 is totally blocked, and the intrusion of water from the introduction hole 24 into the wiring retractor 1 is effectively suppressed.

  As in the case of the first embodiment, such a roof structure has the wiring 8 connected to the rooftop equipment 10 when the rooftop equipment 10 such as the solar cell module 101 is installed on the roof. Provided when retracted indoors.

  When the solar cell module 101 is installed, one wiring lead-in tool 1 is provided for each of a certain number of solar cell modules 101, and one wiring 8 connected to the certain number of solar cell modules 101 is provided. It may be drawn indoors from the wiring lead-in tool 1. In this embodiment, even when a plurality of wires 8 routed from different positions are drawn indoors from one wire drawing tool 1, the wires 8 are positioned by the guide ribs 22 in the hollow portion 23 in this embodiment. Therefore, the plurality of wirings 8 can be easily accommodated in the hollow portion 23. Furthermore, since the wiring 8 is sandwiched between the base body 4 and the pressing member 47 in the hollow portion 23, the movement of the arrangement position is further restrained, so that the plurality of wires 8 can be more easily accommodated in the hollow portion 23.

  Further, since the plurality of wirings 8 are arranged and arranged in the hollow portion 23, stress from the plurality of wirings 8 to the wiring retractor 1 is difficult to concentrate, and thus the wiring 8 and the wiring retractor 1 are not easily damaged. Become. Furthermore, at the time of maintenance after the solar cell module 101 is installed, the correspondence relationship between the wiring 8 and the solar cell module 101 to which the wiring 8 is connected can be easily recognized. It becomes easy.

  Often, a plurality of indoor equipment devices 10 are installed on the roof. In such a case, a plurality of wires 8 are simultaneously drawn indoors from the wire retractor 1. For this reason, the operation of pulling in the wiring 8 at the time of construction becomes complicated, and it becomes difficult to distinguish between the plurality of wirings 8 at the time of maintenance after the construction. Further, the stress applied to the wiring retractor 1 from the plurality of wirings 8 is concentrated at one point, and there is a possibility that the wiring retractor 1 is damaged. However, in the present embodiment, since the guide ribs 22 for guiding the plurality of wires 8 one by one from the introduction hole 24 to the lead-out hole 21 are formed in the hollow portion 23, the wire drawing tool 1 is used. Then, when the work for drawing a plurality of wires 8 from the outdoor to the indoor is performed on the roof, the work for drawing the wires 8 is facilitated and the maintenance after the work is facilitated, and the wire drawing tool 1 from the plurality of wires 8 is provided. It becomes difficult for stress to concentrate.

  Furthermore, if the markings 418, 419, and 420 are formed on the base body 4, it is easy for an operator to place a plurality of wirings 8 at predetermined positions when installing the wiring lead-in tool. In addition, the type of the wiring 8 can be easily discriminated at the time of maintenance after construction and the maintenance is further facilitated.

  Further, similarly to the first embodiment, also in this embodiment, the water drainage piece 57 inhibits the movement of water into the through hole 61 of the roof base 6 and suppresses the intrusion of water into the room.

  Further, since the lower member 3 is installed on the roof base 6, movement of the water on the roof base 6 to the through hole 61 is blocked by the lower member 3. Even if water moves toward the through hole 61 on the lower member 3, the movement of this water is blocked by the cylindrical rib 32. Even when water enters the hollow portion 23, the movement of the water to the through hole 61 is blocked by the cylindrical rib 32. Thereby, the penetration | invasion of the water to an indoor is further suppressed.

  Also in this embodiment, as in the case of the first embodiment, as shown in FIGS. 8A and 8B, the lower member 3 may be provided with a sealing material 34 and a sealing material 35. In this case, similarly to the case of the first embodiment, the intrusion of water into the room is further suppressed by the sealing material 34 and the sealing material 35.

  In addition, the hollow portion 23 of the wiring retractor 1 is opened to the outside through the introduction hole 24, and the introduction hole 24 opens at the end face on the eaves side of the wiring retractor 1. For this reason, even if water flows on the roof material 7 along the inclination of the roof to the eaves side, this water is less likely to enter the hollow portion 23 through the introduction hole 24. Moreover, since the introduction hole 24 is closed by the sealing material 90 (91, 92) and the wiring 8 as described above, the intrusion of water from the introduction hole 24 is further reliably suppressed. Even if water is blown up by wind or the like on the roofing material 7 and flows toward the ridge along the slope of the roof, the introduction hole 24 is blocked as described above, so Insufflation is blocked. This further suppresses the intrusion of water indoors.

  Further, even if water enters the base body 4 in the wiring retractor 1 from the outside on the ridge side, the water is first dammed up by the rib 410 on the ridge side of the water flow control unit 412, and then on the ridge side. The rib 410 flows to the eaves side through the water drainage inlet hole 413. The water is further dammed by the eave-side rib 411 and then flows further to the eave side through the drain hole 413 of the eave-side rib 411. In this way, the water flow is controlled by the water flow control unit 412 so that the water does not flow at once. At this time, water gradually flows from the drainage inlet hole 413 of the eave-side rib 411, and this water flows away from the outlet hole 21, and the outlet hole 21 is surrounded by the surrounding rib 415. Therefore, the intrusion of water into the outlet hole 21 is suppressed. This water further reaches the eaves side end of the base body 4 and flows out from the drain hole 414 to the outside. This further suppresses the intrusion of water indoors. Further, since the fixing hole 44 is opened by a protruding portion 417 formed on the upper surface of the base body 4 and projecting upward, even if water flows on the base body 4, this water is discharged from the fixing hole 44. Entering indoors is suppressed.

  In addition, the structure of the wiring drawing tool 1 which concerns on this invention is not restrict | limited to said each embodiment, unless it deviates from the range and objective of this invention, For example, the structure of each embodiment may be removed partially. The configuration may be partially diverted between the embodiments, or other appropriate design changes may be made.

  Further, the roof structure according to the present invention is not limited to each of the above-described embodiments, and for the appropriate purpose other than the case where the rooftop equipment 10 such as the solar cell module 101 is installed on the roof, It can be applied to pull the wiring 8 from the outside to the inside. In addition, the roof structure according to the present invention has a case where the rooftop equipment is installed on the roof by an appropriate method other than the above embodiments, even when the rooftop equipment 10 such as the solar cell module 101 is installed on the roof. Can be applied to.
